This video optical illusion was another finalist for the 2017 Best Illusion of the Year Contest. It was created by Kokichi Sugihara from Meiji University in Japan.

Three objects that appear to be identical, are reflected in a mirror. Oddly enough, different parts of each of the three objects disappear. For the first object (on the far left), the rooster at the bottom disappears in the reflection. For the middle object, the entire upper half of the structure disappears, and for the third object (located on the far right), the entire lower half disappears. When the objects are rotated and the backs are shown, it is revealed that each object is built differently. From one fixed angle they all look the same, but this is not the case at all.
